This power consumption is negligible. The The 10 cameras plus 24 hours can consume about once electricity

Q:What kind of monitoring camera is used in the store? 360 ° with the introduction of ordinary

If you consider the general monitoring, select the analog camera, ordinary video recorder (remember with a hard disk), plus a display, the estimated cost of 1000-1500 or so.

Q:What is the difference between a dome camera, a gun camera and a dome camera in security monitoring?

Hemisphere is generally installed ceiling, the bolt is installed on the wall, whether with infrared light, the size of the lens according to the actual situation and customer requirements to consider. The dome can be rotated 360 degrees, set the preset position can be automatically cruise, you can automatically zoom to the center of the scene picture auto focus, keep the image clear, you can also manually focus.

Q:There are cameras at the fork in the expressway

The third is to monitor the camera, this camera has a spherical, cylindrical, square box and so on. Some of these cameras with LED lighting device, at night to keep the light to ensure that the camera vision clear. Set the purpose of these cameras is mainly to capture the various types of information applied to the security prevention and control, according to the image records that the facts of the case, locked so that arrested all kinds of criminal suspects

Q:How to monitor the camera with the venue, what type of camera installed in what kind of site, the camera installed how much the number of lenses should be equipped with light board.

Production of the camera all know, whether it is LED light board or array light board, as long as the infrared light board are divided degrees. Commonly common are 30 °, 45 °, 60 ° and 90 °. Lens and light board with 30 ° with 12mm and 16mm, 45 ° with 8mm, 60 ° with 6mm, 90 ° with 3.6mm or 4mm.

Generally the case is the reason for static electricity, in theory, if your camera is using a transformer, that is DC power supply, then basically can be excluded from the leakage caused by the low-voltage (DC12V) camera, if There is a strong power into the words, then the camera will not be able to use, and here to note is not only the camera will have static electricity on your own may also have static electricity, you may say the same two cameras have a One is not, but you have to know the principle of electrostatic discharge, only when you come into contact with the conductive body when the static electricity can be released, you will have the feeling of Ma. In fact, if the camera is used properly, you do not have to worry about whether it is with static electricity, if you really worry, you can ground the camera, the general ceiling has a fire pipe and bridge, you can choose them to ground.
